摘　　要：随着人们生活水平的提高,也逐渐重视环境的治理。垃圾的分类收集是实现垃圾循环利用的一个有效手段,由于目前的垃圾分类技术还未成熟,该设计仅针对易拉罐、玻璃瓶、塑料瓶和废纸4种类型可回收垃圾进行分类收集。该设计是一种基于STM32的4种语音控制垃圾桶,采用STM32单片机作为微处理器,该系统由语音识别模块、语音输出模块、短信提醒模块、舵机系统、垃圾桶溢出传感器和电源模块等组成。通过语音识别技术对声音信号进行处理后,控制垃圾桶识别语音并通过打开盖子进行响应。5 s后,盖子合上。同时,通过GSM短信提醒模块,在垃圾填充满时发出警报,提醒相关部门及时处理并转移垃圾。With the improvement of people's living standards,there is also a growing emphasis on environmental governance.The classification and collection of garbage is an effective means to achieve garbage recycling.Due to the current immature garbage classification technology,this design only targets four types of recyclable garbage:cans,glass bottles,plastic bottles,and waste paper for classification and collection.This design is a four class voice controlled garbage bin based on STM32,using the STM32 Microcontroller as the microprocessor.The system consists of a speech recognition module,a speech output module,a SMS reminder module,a servo system,a garbage bin overflow sensor,a power module,etc.After processing the sound signal through speech recognition technology,control the trash can to recognize speech and respond by opening the lid.After five seconds,the lid closes.At the same time,through the GSM SMS reminder module,a warning will be issued when the garbage is filled,reminding relevant departments to handle the transferred garbage in a timely manner.
